Answer:
- <u><em>You should expect that the ionic bond in LiBr is stronger than the bond in KBr.</em></u>
<u><em /></u>
Explanation:
The<em> ionic bonds</em> are formed by the electrostatic attraction between the ions, cations and anions.
In KBr the cation is K⁺ and the anion is Br⁻.
In LiBr the cation is Li⁺ and the anion is Br⁻.
You must expect that the bond strength depends mainly on the charges present on each ion and the distance between them.
Nevertheless, the effect of the distance between the radius dominate the trendency of the bond strength, which makes that the ionic strength trend be related to the ionic radius trend.
Lithium is a smaller ion than Potassium (both are in the same group and Lithium is above Potassium).
Thus, you should expect that the Li ion is closer to the Br ion than what the K ion is to the Br ion and expect that the bond between a Li ion and the Br ion be stronger than the bond between the K ion and the Br ion.

sorry can you snap this cause i dont get what are u asking forr i would like to help you insteadd
Answer:1 atm = 101,325 Pa
So, you convert 33.7 KPa to Pa and divide by 101,325, as follows:
3.7 KPa (1 x 10^3Pa / 1 KPa) (1 atm / 101,325 Pa) = .33 atm
As you can see 33.7 KPa, which is equal to .33 atm, is greater than 0.25.
